Hi, I created my block design by using axi interrupt controller to get rid of the key error. I connected the interrupts to concat IP and connected the output of concat to the input of axi interrupt controller, and connected its output to the IRQ_F2P[0:0] in the zynq PS, when I do this connection, I am getting a type mismatch error as shown below.

WARNING: [BD 41-1731] Type mismatch between connected pins: /axi_intc_0/irq(undef) and /processing_system7_0/IRQ_F2P(intr)

I will attach my block design below, please help me with your input.

You have an output port on the interrupt controller that has a type. Thay type does not match the interrupt input port on the PS. You should not just bypass this and connect the wire of the output port to the PS.
You need to change the configuration for the Interrupt controller Interrupt output connection to single. You should then be able to connect the two ports.
